Problems solved by technology

However, the holographic transfer paper currently produced can only be used in seamless technology if it is suitable for gravure printing. If the positioning holographic pattern is used, the pattern and the graphic information on the gravure printing cylinder cannot be registered. In the process, there will also be cumulative errors and deviations

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] The transfer method of the holographic anti-counterfeiting pattern suitable for gravure positioning overprinting of the present invention comprises the following steps:

[0023] The first step: using a large-format full-page lithography equipment to make a full-page laser version A with a positioning pattern B (see figure 1 ), the size of the positioning pattern B is designed according to the gravure printing typesetting diagram, the accuracy of the positioning pattern B reaches ±0.01mm, and a holographic positioning mark C is made next to each positioning pattern B;

[0024] The second step: use a PET base film with a thickness of 18 μm, and coat a layer of transferable acrylic wax coating with moldability on the base film;

[0025] Step 3: Use molding equipment to emboss the positioning pattern B and holographic positioning mark C on the laser plate A on the acryl...

Abstract

The invention discloses a transferring method of holographic anti-counterfeiting patterns suitable for gravure positioning overprinting. The transferring method comprises the following steps that a laser plate provided with positioning patterns is manufactured, and a holographic positioning mark is manufactured near each positioning pattern; a base film is coated with a transferring acrylic acid lacquer coating layer with a mould pressing property; the locating patterns and the holographic positioning marks on the laser plate are embossed on the acrylic acid lacquer coating layer on the base film; the face, provided with the positioning patterns, on a positioning holographic film is aluminized in a vacuum mode; paper and the positioning holographic transfer film are composited; the positioning holographic paper is dried through a drying oven to be formed; the base film in the formed positioning holographic paper is peeled off and finally the coating carrying the positioning holographic patterns is kept on the paper. The transferring method of the holographic anti-counterfeiting patterns can effectively control the relative positions of all the positioning patterns of the transfer film and the size deviation between the holographic positioning marks on the transfer film and printing positioning marks on the paper.

Description

technical field [0001] The invention relates to a transfer molding and compounding technology, in particular to a transfer method of a holographic anti-counterfeiting pattern suitable for gravure positioning and overprinting. Background technique [0002] The existing holographic pattern transfer method is to coat the base film, transfer the holographic pattern to the coating by a molding method, then carry out aluminum plating, and finally transfer the holographic pattern to the paper. Since the holographic pattern is made on the laser plate, the size of each laser plate is fixed. After transferring to holographic paper, it can only be cut to the same size and then offset to achieve positioning overprinting. With the continuous improvement and improvement of printing technology, the fine dot transition printing level that can only be realized on offset printing can be well reflected in gravure printing, so more and more printed products have begun to turn to gravure printin...
